几个常用的SharePoint对象模型的有用函数
最近在开发东莞国税网上办税报表系统，用到SharePoint2007+Infopath Service作为表单服务器，后台数据存储采用Oracle，其中涉及了管理模板的需求，要对SharePoint对象模型进行操作，研究了2天sharepoint sdk,代码完成如下：

dirPath=string.Format("{0}/{1}",list.ParentWeb.ServerRelativeUrl,dirPath);
SPListItem folderItem = list.ParentWeb.GetListItem(dirPath);

return folderItem.Folder;
else
return null;
